| 摘要 |
The invention relates to a sintered coupling ring (1) which comprises a rim of coupling teeth (2) which is provided with wedge-shaped front surfaces (3, 4), which intersect on an axial plane, and flanks (5) which are inclined towards the base of the tooth according to an inclination angle of teeth backs (6). The flanks (5) are indented from a protruding, axis-normal shoulder (7). The aim of the invention is to provide advantageous conditions for a moulding form of the flank indentations such that the intersection planes between the wedge-shaped front surfaces (3, 4) extend to the outside of the centre of the tooth and that the shoulders (7), which are offset in an axial manner in relation to each other (7), of both of the flanks (5) of the coupling teeth (2) separate the indented flanks (5) by a flank part (8) which is essentially triangular, is parallel to the axis and which is adjacent to the front surfaces (3, 4).
